I can only speak for myself. I can absolutely guarantee that nothing posted on my board will be deleted unless it has a mean spirited tone. This may seem rather general but I think everyone knows when something has been posted to demean another poster. The only rule I have is to respect the other posters on my board. As long as you do that, you will never have a post deleted. As I said before, the question hasn't come up for me yet. I've never deleted anything other than spam of duplicates and I don't really foresee my ever having to do so.
